CLEANSING FILTER.

SPECIFICATION forming art of Letters Patent No.-685,159, dated October 22, 1901. Application filed ll'uly 16, 1900; Serial No. 23,813. (No model.)

away the residue or filtrate from time to time accumulating in it.

In order to make the invention clear, I will describe same with reference to the accompanying sheet of drawings, in which Figure 1 represents a front elevationof the filter; Fig. 2, an end elevation; Fig. 3, a longitudinal vertical section; Fig. 4, a detail of a valve and rod employed; Fig.5, alongitudinal View of the scraper-brush detached; Fig. 6, a

cross-section through scraper-brush and filtering-body; Fig. 7, a detail of gauze strainer and its connections employed at entrance to filter; Fig. 8, a cross section through gauze.

In a water-service pipe or tap 1 I form an opening at side with socket 3, having internal screw-thread to receive the end 2 of cylinder 4. The cylinder end 2 has screw portion entering socket, a washer 5 being employed between cylinder and socket. The other end of the cylinder is closed in with'water-tight construction and is provided with a small tap for the outlet of filtered water. The construction of this part is as follows: 6 represents the end of cylinder, which is held in position by cap 7 and is stepped, so as to form a bearing for end of scraper-barrel 8, and recessed to hold end of tube 9, of filtering material. A hole 10 passes through center of this cylinder end, and it has'projecting screwed portion 11, the end of which forms seating for filter tapvalve. Asmall cylinder 12 screws on the said portion 11 and which has outlet-pipe for filtered water. A tap-spindle 14 screws into end of small cylinder 12. This spindle is hollow and receives rod 15 of valve 16 and is provided with handle 17. The small cylinder 12 is closed by a cap 18. V

The main cylinder 4 has a pipe 20 communicatingwith it, which meets a down-pipe 21,

also connected with main cylinder.

A hollow shaft 22 is screwed into the end 2 of the cylinder 4. This shaft (see Fig. 7)

is stepped and has flange 23 upon it, which abuts against end of cylinder. A hollow tube 24 enters one end of hollow shaft and which is recessed to receive the end of strainer 25, which is constructed of spirallyrolled wire-gauze, closed at its end with cap 26. The'tube 24 has flange 27 upon it, with leather washers 28 29 on either side of it to form a Water-tight joint at its connection with the water-service pipe on tap 1. The hollow shaft 22 carries loosely at its other end beveled-toothed wheel 30, which is held between stop-collars 31 and 32 on shaft. The face of the beveled wheel carries projecting pins 33, which enter holes formed in end of scraperbarrel 8. The end of hollow shaft 22 also projects through a hole formed in end of barrel.

The beveled toothed wheel 30 gears with corresponding beveled-toothed wheel 35, set upon rod 36. This wheel is supported upon bracket 37, secured to end of cylinder. The rod 36is set in the pipe 21 and has square end 57. A sleeve 38 is set upon the round portion of rod 36 and carries washers 39 40, which rest upon flanges on the sleeve, so forming a sliding valve. The square end of the rod enters tap-rod 41, the top of which bears on the valve. This rod is hollowed square to receive square end of valve-rod, so that while rod acts on the valve to raise it the valve-rod and beveled-pinion 35 will remain at a station ary level. The screw-rod 41- terminates in tap-handle 43. This screw-rod passes through screwed portion of pipe 44 and which has out let-pipe 51 and which is screwed into end of v ber strips, and wire-gauze form brushes which act lightly upon the surface of the filteringtnbe 9 and have a certain amount of spring.

The brushes are thus adapted to move over the surface of the filtering-tube in either dircctionforward or backward.

The material of which the porous tube 9 is constructed should vary in porosity to suit the higher or lower pressures of water or other liquids to be filtered, the porosity increasing as the pressure lowers, and vice versa, so that my apparatus may be used either as a low or high pressure filter, as may be predetermined.

The filter is operated as follows: The water from the pipe-service enters the filter through the gauze 25 and is thus screened, the rough sediment being washed away when the tap is turned on. The water thus partially filtered passes through the hollow tube 24 and shaft 22 and, being under pressure, passes through the porous filtering-tube to its inside and passes through the outlet-opening 10 at end of cylinder and out by pipe 50 when the tap 17is turned-that is, when the tap 17 is turned the spindle 14 recedes from the opening 10 and the water-pressure will act upon the valve 16, so as to force it back and open the passage to the outer pipe 50. The valve-spindle 15 is thus loose in the recess in the tap-spindle 14. The scraper 8 is rotated whenever the tap 43 is employed. This is the usual household tap, the turning on of which will cause the rod 36 to be rotated, so as to actuate the bevelgearing which is connected with the scraper-barrel, the tap at the same time opening or closing the valve 38, which controls the outlet-pipe 51. The scraper-barrel, with its brushes, is thus revolved around the porous filtering-tube. The water rushing around the outside of said tube carries with it all sediment or slimes that the scraper-brushes have removed. When the tap 43 is turned off again, the scraper-brushes revolve in an opposite direction, thereby completely removing any remaining sediment or slime and which will be carried away on the next turning on of the tap 43.

The filtered water from the interior of porous tube 9 may be obtained at will by turning on the tap 17, which will allow a flow of water by outlet-pipe 50.

Having now particularly described and ascertain ed the nature of my said invention and in what manner the same is to be performed, I declare that what I claim is- 1. In combination a cylinder connected with water-supply pipe, a tubular body of filtering substance set within same and having its inside communicating with outlet-duct for filtered water at end of cylinder, a pipe connected with the cylinder and having a household tap, a scraper-barrel encircling the filterin g-body and having means connected with the household tap whereby it is rotated on the turning on or off of said tap, substantially as and for the purposes set forth.
